Today, ATSC 3.0 includes the Scalable HEVC profile known as SHVC--which enables a base signal to be delivered with high robustness to mobile devices while simultaneously sending an enhancement signal with very low robustness but high reach. This can be used to give HD or 4K enhancement on top of the base video service quality.
ATSC is a platform that allows for innovation. Building on IP and the interactivity of web technologies enables broadcasters to become much more than just a TV service.
This combination of web and broadcast technologies have changed the way broadcasters operate in the modern world. Hybrid delivery, or rather broadcast in combination with broadband, represents one of the early use cases proposed. This leverages the broadcast and multicast scale of over-the-air transmissions—enabling broadcasters to reach an entire city from one tower with one signal—while also harnessing the interactivity and personalization of broadband.
